I am attempting to set up a new cisco router at my workplace. the router will make a vpn connection with a vendor of ours. We currently have a t1 line from att, fake ip of 1.1.1.0 and mask of 255.255.255.248. if i am understanding correctly, that means i can have up to 6 devices with a wan ip of 1.1.1.1 to 1.1.1.6?

Is the t1 an internet t1 or a private link t1? If it is an internet t1 you might try using a subnet in the 10.x.x.x range, so that routing to websites with a 1. subnet will still be routed properly. Even if it is a private t1 you still should do this to keep the internet traffic routing properly.
